Newest report Nov 13: Andes hantavirus confirmed transmissible person-to-person in South America (El Nacional).from the newest member report, published 13 Nov 05:00 UTC
Why it matters
Confirmation of person-to-person transmission and geographic origin is critical for public health containment strategies and understanding zoonotic disease spread in travel settings.

key facts by their own evidence status

Known

None of the key facts is established by the evidence yet.

Not established

  • Person-to-person transmission of hantavirus in Argentina is confirmed, linked to Patagonia strains.
  • The Andes virus, endemic in Argentina and Chile, is confirmed to spread through close, direct, prolonged contact.
  • The initial hantavirus infection on a cruise ship (MV Hondius) originated in Argentine Patagonia.
  • Transmission routes on the MV Hondius did not follow expected patterns, highlighting unpredictability.
  • The specific outbreak location and scale within Argentina remain largely unspecified.

Indicators to watch

  • →Specific geographic locations and scale of the ongoing outbreak in Argentina
  • →Effectiveness of containment strategies given confirmed person-to-person transmission
  • →Further details on the index case and full transmission chain of the cruise ship outbreak

Read the full assessment

Scientific investigations confirm person-to-person transmission of hantavirus in an ongoing outbreak in Argentina, with genetic links to strains originating in Patagonia. Studies also trace a cruise ship outbreak to Argentine Patagonia, resolving its origin. The specific outbreak location and scale within Argentina remain largely unspecified, though transmission dynamics in confined settings are noted as unpredictable.
